Mwanzo 27:1

Isaki alipokuwa mzee na macho yake yalipokuwa yamekosa nguvu asiweze kuona tena, akamwita Esau mwanawe mkubwa, akamwambia, “Mwanangu.” Akajibu, “Mimi hapa.”

And it came to pass, that when Isaac was old, and his eyes were dim, so that he could not see, he called Esau his eldest son, and said unto him, My son: and he said unto him, Behold, here am I.
